The gardener grows carrot seeds by setting out in the spring carrots which were grown the previous year. After producing seeds the plants die. This is the habit of the wild carrots also. They do not produce seeds the first year. Consequently if they are cut off near the ground two or three times the second year, their life history is finished. Wild carrots do not spread from the roots like the thistle but they produce a great number of seeds. These seeds have been known to live in the ground several years before growing. Therefore, they must be repeatedly pulled or cut off in order to keep a field free from them. They are not trouble- some in plowed land but are common in old meadows. Canada thistle.—This weed is very common, especially in pastures. It also occurs in plowed land. It may be distinguished from other thistles by the root. If one is dug up it will be found to have heavy, roots, called root- stocks, which extend some distance from the plant, parallel with the surface of the ground. These may be six to ten inches below the surface. Every three or four inches new plants grow up from these. One seed in time may produce a large patch of these weeds from the roots alone. The Canada thistle spreads into new fields by means of seeds. These seeds may be sown with clovers, grasses, or even oats. Moreover, the seed has at the top a feathery attachment which permits the seed to. Fig. ^6.—Wild carrot. Please note that these images are ext
